Abstract

This work reports results of dispersion analysis, performed for the fundamental mode of silica microstructured optical fiber (MOF) with six GeO₂-doped cores. We used commercially available software COMSOL Multiphysics® 6.1 with rigorous full vectorial finite element method, while earlier on fabricated and presented MOF with six step-index GeO2- doped cores end face photo image was applied to get averaged parameters for input data. Therefore, modeled multi-core MOF has typical “telecommunication” outer diameter 125 µm, it contains six cores with diameter 9.0 µm and step refractive index profile with height n=0.0275, 121 air holes with diameter 5.0 µm and pitch 7.8 µm. In this work we present results of the fundamental mode 1st…3rd order dispersion parameters, computed over all ratified “telecommunication” wavelength bands.
